Gas burner assembly for an appliance

Abstract

A gas burner assembly includes an elongated burner and a round burner positioned at a middle portion of the elongated burner. The elongated burner defines a plurality of flame ports adjacent a first end portion of the elongated burner. Flame ports of the plurality of flame ports that are positioned on a pair of parallel linear segments of the elongated burner have a first total port area, and flame ports of the plurality of flame ports that are positioned on an arcuate segment of the elongated burner have a second total port area. The second total port area is greater than the first total port area.

       6. The gas burner assembly of  claim 1 , wherein the flame ports of the first plurality of flame ports on the arcuate segment are larger in cross-sectional area than that of the flame ports of the first plurality of flame ports on the pair of parallel linear segments. 
     
     
       7. The gas burner assembly of  claim 1 , wherein the elongated burner and the round burner are defined by a single continuous piece of metal. 
     
     
       8. A gas burner assembly, comprising:
 a round burner; 
 an elongated burner having a first elongated burner portion and a second elongated burner positioned opposite each other about the round burner, the first elongated burner portion having a pair of linear edges and an arcuate edge that extends between the linear edges of the pair of linear edges, the first elongated burner portion also comprising a first plurality of flame ports distributed along the pair of linear edges and the arcuate edge, the flame ports of the first plurality of flame ports positioned at the pair of linear edges having a first total port area, the flame ports of the first plurality of flame ports positioned at the arcuate edge having a second total port area, the second total port area being greater than the first total port area, 
 wherein the second total port area is at least one and one half times greater than the first total port area, 
 wherein a number of flame ports of the first plurality of flame ports on the pair of parallel linear segments is greater than a number of flame ports of the first plurality of flame ports on the arcuate segment, and 
 wherein the arcuate segment connects with each of the pair of linear segments at respective tangent points between curved and linear edges of the elongated burner. 
 
     
     
       9. The gas burner assembly of  claim 8 , wherein the pair of linear edges is a first pair of linear edges and the arcuate edge is a first arcuate edge, the second elongated burner portion having a second pair of linear edges and a second arcuate edge that extends between the linear edges of the second pair of linear edges, the second elongated burner portion also comprising a second plurality of flame ports distributed along the second pair of linear edges and the second arcuate edge, the flame ports of the second plurality of flame ports positioned at the second pair of linear edges having a third total port area, the flame ports of the second plurality of flame ports positioned at the second arcuate edge having a fourth total port area, the fourth total port area being greater than the third total port area.
